i am going out to day to see what is the top powder charge i can safely run,
now my question,when looking for signs of over pressure is it best to measure the part of the case that is just above the extractor ring (in the recess).what size expansion can you go to 1th 2th 3th 4th i know to look at the primers and to check for extractor marks on the case,and harder bolt lift than normal.
it is on a 243 AI 270 tight neck.lapua brass fire formed.
i am asking as i have used my ballistics program to see what powder it says to go up to,and it said 49g of n165 under a 95g vld fed 210 primer.
now i have tried up to 50.2 and can not see any signs yet,
AM I MISSING SOMETHING.
so i am going to keep going till i see some signs,with the checks i have mentioned,will i be able to tell if i am going to far.
